Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit under 35 USC .sctn. 119
of JP Patent Application JP 2019-108301 filed Jun. 10, 2019, the
entire disclosure of which is incorporated herein by reference.
BACKGROUND INFORMATION
[0002] The present invention relates to a sealing structure for a
truck cargo bed with a shutter. The shutter couples to an upper
part of the cargo bed and moves between at least two positions to
open and close an opening of the cargo bed.
[0003] There are a variety of automobiles with a shutter 100 as
illustrated in FIG. 1. The shutter 100 moves between at least two
positions to open and close an opening on an upper part of a cargo
bed 1.
[0004] The shutter 100 couples to the cargo bed 1 by a left track
201 and a right track 301. The left and right tracks 201, 301 are
mounted on top edges of a left side wall 2 and a right side wall 3.
The left and right side walls 2, 3 are vertically mounted on a left
end and a right end of the cargo bed 1. A tailgate 5 is mounted on
a rear end of the cargo bed 1 and is pivotal in a front and rear
direction of an automobile body.
[0005] The tailgate 5 in a closed position and the left and right
side walls 2, 3 surround the cargo bed 1. The shutter 100, when
fully extended from a front part of the cargo bed 1 to the rear
end, shuts an entire cargo area to close the opening on the upper
part of the cargo bed 1.
[0006] There are a variety of sealing structures for surroundings
of the tailgates.
[0007] For example, Japanese Unexamined Patent Application
Publication No. 64-056281 is directed to a cover having three
panels to cover the cargo bed. A gate is mounted on a rear part of
the cargo bed and is pivotal in the front and rear direction of the
automobile body. The gate, a left side wall surface, and a right
side wall surface surround the cargo bed. A weather strip is
attached to upper edges of the gate and the left and right side
wall surfaces to seal a space between the cargo bed and the three
panels when the cover is fully extended.
[0008] Japanese Patent No. 3033810 is directed to a fixed canopy, a
movable canopy, and a back window glass to cover the cargo bed. The
weather strip is attached to the fixed canopy and the movable
canopy to seal a space between the canopies and the cargo bed or
the back window glass.
[0009] Japanese Unexamined Patent Application Publication No.
64-056281 and Japanese Patent No. 3033810 are not directed to the
truck cargo bed 1 with shutter 100 as illustrated in FIG. 1. In
addition to the difference between shutter 100 and the members to
cover the cargo bed, Japanese Unexamined Patent Application
Publication No. 64-056281 and
[0010] Japanese Patent No. 3033810 merely disclose the linear
weather strips, and do not disclose the sealing structure for
connecting parts among a plurality of members at upper parts of a
left rear end and a right rear end of the cargo bed 1.
[0011] While the weather strip seals the linear space between the
shutter 100 and tailgate 5 of the truck, a part Z in FIG. 1 is hard
to seal, and water enters the cargo bed 1 through a space in the
part Z. The part Z indicates the upper parts of the left and right
rear ends of the cargo bed 1.
[0012] This configuration imposes limitations such as putting a
cargo into a front part of the cargo bed 1 to protect the cargo
from water.
[0013] Therefore, an object of the present invention is to provide
a sealing structure excellent in sealing performance at the upper
parts of the left and right rear ends of the cargo bed for the
truck with the shutter.

(110) is folded toward the front part of the automobile body such
that the inner wall (113) has an L-shaped cross section.
[0028] Symbols in parentheses show constituents or items
corresponding to the drawings.
[0029] According to the present invention, when the shutter is
fully extended with the tailgate closed, the shutter seal member
provided on the rear end of the shutter makes elastic contact with
the tailgate. Also, the touch member provided on the left side end
and the right side end of the rear part of the shutter touches the
first and second seal beads on the upper surface. The first and
second seal beads are provided on the upper wall of the protrusion
of the bed liner seal member, and extend in the right and left
direction of the automobile body.
[0030] With this configuration, upper parts of the rear ends of the
left side wall and the right side wall of the cargo bed are
sufficiently sealed, and infiltration of water into the cargo bed
from the exterior of the automobile is prevented.
[0031] In addition, as measures against abrasion, the shutter
touches the beads, and does not make elastic contact with lips or
hollow members. The beads are increased in thickness and high in
rigidity. The lips and the hollow members are reduced in thickness
and low in rigidity. With this configuration, the beads, subjected
to repeated elastic contact over a long period of time, are
prevented from tears or damages. Even in case the beads are worn
down, foams in the beads, which are increased in thickness and high
in rigidity as compared with the lips or the hollow members, are
hard to appear on a surface and do not degrade appearance.
[0032] In addition, the shutter seal member provided on the rear
end of the shutter makes elastic contact with the tailgate seal
member, not the tailgate directly. The tailgate seal member is
provided on the upper part of the front surface of the tailgate.
With this configuration, paint on tailgate, which is a member of
the automobile body, is prevented from peeling off.
[0033] In addition, when the shutter is fully extended, the touch
member of the shutter also touches the third and fourth seal beads
on the side surface. The third and fourth seal beads are provided
on the side wall of the protrusion of the bed liner seal member,
and extend in the upper and lower direction of the automobile body.
With this configuration, sealing function is further improved.
[0034] In addition, the first and second seal beads on the upper
surface are the two beads parallel with each other. The third and
fourth seal beads on the side surface are the two beads parallel
with each other. The first and second seal beads are continuous
with the third and fourth seal beads. With this configuration, the
upper parts of the rear ends are sufficiently sealed without a
break.
[0035] In addition, the first gutter is formed beneath the
protrusion of the bed liner seal member and is closer to the front
part of the automobile body than the protrusion. The first gutter
extends in the right and left direction of the automobile body. The
second gutter is formed beneath the third and fourth seal beads on
the side surface and is closer to the interior of the automobile
than the side wall of the protrusion of the bed liner seal member.
The second gutter extends in the front and rear direction of the
automobile body and is continuous with the first gutter. With this
configuration, water around the bed liner seal member is guided
into the first gutter and the second gutter. Especially, with the
configuration that the first and second seal beads on the upper
surface are continuous with the third and fourth seal beads, a
channel between the two beads weakens force of water which passes
through the channel, and guides water into the first gutter. With
this configuration, water is prevented from splashing.
[0036] In addition, the hole closer to the rear part of the
automobile body than the second gutter drains water guided into the
first and second gutters toward the exterior of the automobile.
With this configuration, water does not collect on the first or
second gutter or overflow.
[0037] In addition, the touch member includes the upper wall, the
side wall, and the inner wall. When the shutter is fully extended,
the lower surface of the upper wall of the touch member touches the
first and second seal beads on the upper surface, and the outer
side surface of the side wall touches the third and fourth seal
beads on the side surface. With this configuration, the upper parts
of the rear ends are stably sealed. Also, the lower surface of the
inner wall makes elastic contact with the first wall, and the lower
surface of the side wall makes elastic contact with the second
wall. With this configuration, infiltration of water into the cargo
bed from the first gutter or the second gutter is prevented.
[0038] In addition, the lower end of the inner wall of the touch
member is folded toward the front part of the automobile body such
that the inner wall has the L-shaped cross section. With this
configuration, when the shutter is extended toward the rear part of
the automobile body from the front part to close the opening of the
cargo bed, the lower end of the inner wall of the touch member is
not unnecessarily bent, by catching the first wall.

cargo bed 1. A stay 7 connects a center of a left end of the
tailgate 5 with a center of a rear end of the left side wall 2. A
stay 8 connects a center of a right end of the tailgate 5 with a
center of rear end of the right side wall 3. The tailgate 5 is
pivotal in the front and rear direction of the automobile body with
a lower end part of the tailgate 5 as a pivotal axis. The tailgate
5 in a closed position and the left and right side walls 2, 3
surround the cargo bed 1.
[0059] The shutter 100, when fully extended with the left and right
side walls 2, 3 as well as the tailgate 5 in the closed position
surrounding the cargo bed 1, covers an entire opening of the cargo
bed 1 as illustrated by a broken line in FIG. 1.
[0060] As illustrated in FIG. 3, a shutter seal member 120 is
provided on a rear end of the shutter 100. The shutter seal member
120 faces downward, is hollow, and extends in a right and left
direction of the automobile body. The shutter seal member 120 makes
elastic contact with a tailgate seal member 6 when the tailgate 5
is in the closed position and prevents infiltration of water from a
space between the shutter 100 and the tailgate 5. The tailgate seal
member 6 is provided on an upper part of a front surface of the
tailgate 5. The tailgate seal member 6 includes an installation
base member 6a and a seal lip 6b. The installation base member 6a
has a U-shape with an opening on a lower end. The seal lip 6b
extends from an upper wall of the installation base member 6a and
makes elastic contact with the shutter seal member 120
directly.
[0061] As illustrated in FIG. 1, a bed liner 9 on the left and a
bed liner 9 on the right are provided on the rear ends of the left
and right side walls 2, 3, which are vertically mounted on the left
end and the right end of the cargo bed 1. The bed liners 9 protrude
toward an inner side of the cargo bed 1. A bed liner seal member 10
is provided on rear side surfaces of the bed liners 9.
[0062] As illustrated in FIG. 4, the bed liner seal member 10
includes a protrusion 11. The protrusion 11 has a shape of a
quadrangular prism and protrudes upward. While in FIG. 9, an insert
15 is embedded in the bed liner seal member 10 to increase rigidity
of the bed liner seal member 10, this should not be construed in a
limiting sense. Another possible embodiment is that an outsert is
embedded in the bed liner seal member 10 instead of the insert 15.
Still another possible embodiment is that the outsert as well as
the insert 15 is embedded in the bed liner seal member 10.
[0063] As illustrated in FIG. 4, first and second seal beads 21, 22
on an upper surface are provided on an upper wall 12 of the
protrusion 11. The first and second seal beads 21, 22 are parallel
with each other and extend in a right and left direction of the
automobile body. Also, third and fourth seal bead 23, 24 on a side
surface are provided on a side wall 13 of the protrusion 11. The
third and fourth seal bead 23, 24 are parallel with each other and
extend in an upper and lower direction of the automobile body. The
side wall 13 is close to an inner side of the cargo bed 1.
[0064] Material for use as the bed liner seal member 10 includes
rubber-like elastic body. Examples of the rubber-like elastic body
include synthetic rubber material such as EPDM. Examples of the
rubber-like elastic body also include thermoplastic resin such as
olefinic thermoplastic resin. The rubber-like elastic body may be
foamed or non-foamed depending on hardness of the material.
Alternatively, foamed rubber-like elastic body or non-foamed
rubber-like elastic body may be used according to a position in the
sealing structure.
[0065] An interval between the first and second seal beads 21, 22
is the same as an interval between the third and fourth seal beads
23, 24, and forms a channel. The first seal bead 21 is continuous
with the third seal bead 23. The first and third seal beads 21, 23
are close to a front part of the automobile body. The second seal
bead 22 is continuous with the fourth seal bead 24. The second and
fourth seal beads 22, 24 are close to a rear part of the automobile
body. A connecting part between the first and third seal beads 21,
23 and a connecting part between the second and fourth seal beads
22, 24 are chamferred off and have curved surfaces (round
surfaces). As illustrated in FIG. 10, which is an enlarged
cross-sectional view of the bed liner seal member taken along line
X-X of FIG. 4, the first and second seal beads 21, 22 are longer in
width in the front and rear direction of the automobile body than
height in the upper and lower direction of the automobile body.
[0066] Another possible embodiment is that the first and second
seal beads 21, 22 have the same length in width and height. Still
another possible embodiment is that the first and second seal beads
21, 22 are longer in height than width. But the first and second
seal beads 21, 22, which are longer in width than height, are
improved in rigidity and prevented from abrasion, and therefore,
are more preferable.
[0067] As illustrated in FIG. 11, which is the enlarged
cross-sectional view of the bed liner seal member taken along line
XI-XI of FIG. 4, base roots of the third and fourth seal beads 23,
24 are increased in thickness as compared with top ends. Also, the
top ends of the third and fourth seal beads 23, 24 gradually lean
toward the rear part of the automobile from the front part.
[0068] As illustrated in FIGS. 4 and 10, a first gutter 25 is
formed beneath the protrusion 11 of the bed liner seal member 10
and is closer to the front part of the automobile body than the
protrusion 11. The first gutter 25 extends in the right and left
direction of the automobile body. The first gutter 25 is formed
between a first wall 26 and a wall of the protrusion 11 closest to
the front part of the automobile body. The first wall 26 extends in
the right and left direction of the automobile body, and is higher
than a bottom surface of the first gutter 25 and lower than an
upper wall 12 of the protrusion 11.
[0069] As illustrated in FIG. 4, a second gutter 27 is formed
closer to the interior of the automobile than the side wall 13 of
the protrusion 11 of the bed liner seal member 10. The second
gutter 27 extends in the front and rear direction of the automobile
body. The second gutter 27 is formed between a second wall 28 and
the side wall 13 of the protrusion 11. The second wall 28 extends
in the front and rear direction of the automobile body, and is
higher than a bottom surface of the second gutter 27 and lower than
the upper wall 12 of the protrusion 11.
[0070] The second gutter 27 is formed beneath the third and fourth
seal beads 23, 24, and lower ends of the third and fourth seal
beads 23, 24 connect with the bottom surface of the second gutter
27.
[0071] The first gutter 25 and the second gutter 27 are continuous
and form an L-shape. The bottom surface is gently lowered toward
the second gutter 27 from the first gutter 25. In addition, a hole
29 is formed on an extension of the second gutter 27, that is a
position closer to the rear part of the automobile body than the
second gutter 27. The hole 29 drains water guided into the first
and second gutters 25, 27 toward an exterior of the automobile. The
first wall 26 and the second wall 28 are connected with each other
and continuous.
[0072] On a left end and a right end of the automobile body as
illustrated in FIG. 6, the seal lip 6b of the tailgate seal member
6 directly makes elastic contact with a rear part of the bed liner
seal member 10 relative to the automobile body.
[0073] The shutter seal member 120 and the tailgate seal member 6
may be made of the same material as the bed liner seal member
10.
[0074] An extra member high in rigidity may be embedded in the
installation base member 6a of the tailgate seal member 6.
[0075] As illustrated in FIG. 5, a touch member 110 is provided on
a left side end and a right side end of a rear part of the shutter
100, and makes elastic contact with the bed liner seal member 10
when the shutter 100 is fully extended.
[0076] The touch member 110 is integrally formed with a left side
end and a right side end of a rear part of the end cap 101, made of
resin. The touch member 110 includes an upper wall 111, a side wall
112, and an inner wall 113. The side wall 112 extends downward from
a part of the upper wall 111 closest to the interior of the
automobile and in the front and rear direction of the automobile
body. The inner wall 113 extends downward from a part of the upper
wall 111 closest to the front part of the automobile body and in
the right and left direction of the automobile body. Also, the
lower end of the inner wall 113 is folded toward the front part of
the automobile body such that the inner wall 113 has an L-shaped
cross section. A lower surface of the inner wall 113 is as high as
a lower surface of the side wall 112 and the lower surfaces form a
uniform surface.
[0077] When the shutter 100 closes the opening of the cargo bed 1
as illustrated in FIG. 13 after the shutter 100 is extended toward
the rear part of the automobile body from the front part as
illustrated in FIG. 7, the shutter 100 makes elastic contact with
the bed liner seal member 10 as illustrated in FIG. 9.
Specifically, the lower surface of the upper wall 111 of the touch
member 110 touches, not compresses, the first and second seal beads
21, 22 from an upper side, and an outer side surface of the side
wall 112 of the touch member 110 touches, not compresses, the third
and fourth seal beads 23, 24 from a lateral side. Also, the lower
surface of the inner wall 113 of the touch member 110 makes elastic
contact with the first wall 26, which forms a part of the first
gutter 25, from the upper side, and the lower surface of the side
wall 112 of the touch member 110 makes elastic contact with the
second wall 28, which forms a part of the second gutter 27.
[0078] While in the present embodiment, as illustrated in FIG. 9,
the upper wall 111 and the side wall 112 of the touch member 110
touch, not compress, the first and second seal beads 21, 22 and the
third and fourth seal beads 23, 24, respectively, this should not
be construed in a limiting sense. Another possible embodiment is
that the upper wall 111 and the side wall 112 slightly compress the
first and second seal beads 21, 22 and the third and fourth seal
beads 23, 24, respectively.
[0079] With the configuration of the present embodiment, the seal
beads 21, 22, 23, 24 are hard to wear down even after the shutter
100 opens and closes the opening of the cargo bed 1 repeatedly.
[0080] In addition, it is possible that the seal beads 21, 22, 23,
24 do not touch the touch member 110 and a small space remains
between the touch member 110 and the seal beads 21, 22, 23, 24 due
to deviation in positional relation among the bed liner seal member
10, the cargo bed 1, and the shutter 100 as well as deviation in
shape or size. Even in case the small space remains, since the
first and second seal beads 21, 22 are continuous with the third
and fourth seal beads 23, 24, the channel between the two beads
weakens force of water which passes through the channel and guides
water into the first gutter 25. With this configuration, water is
prevented from splashing.
[0081] In addition, the hole 29 closer to the rear part of the
automobile body than the second gutter 27 drains water guided into
the first and second gutters 25, 27 toward the exterior of the
automobile. With this configuration, water does not collect on the
first or second gutter 25, 27 or overflow.
[0082] Another possible embodiment is that the upper wall 111 and
the side wall 112 of the touch member 110 are slightly closer to
the seal beads 21, 22, 23, 24 to increase elastic contact force.
But the upper wall 111 and the side wall 112 of the touch member
110 preferably approach the seal beads 21, 22, 23, 24 to the extent
not to damage the seal beads 21, 22, 23, 24 in consideration of the
deviation in positional relation.
[0083] FIG. 5 illustrates imaginary lines 21aL, 22aL, 23aL, 24aL
with broken lines on the touch member 110. The imaginary lines
21aL, 22aL, 23aL, 24aL are positions on the touch member 110 which
top ends 21a, 22a, 23a, 24a of the seal beads 21, 22, 23, 24 touch,
not compress, respectively, when the shutter 100 is fully
extended.
[0084] According to the embodiment of the present invention, the
tailgate 5 in the closed position as illustrated in FIG. 3 makes
elastic contact with the bed liner seal member 10, provided on the
rear ends of the left and right side walls 2, 3.
[0085] When the shutter 100 is fully extended with the tailgate 5
closed, the shutter seal member 120, provided on the rear end of
the shutter 100, makes elastic contact with the tailgate 5 as
illustrated in FIG. 13. Also, as illustrated in FIG. 10 and FIG.
11, the touch member 110, provided on the left side end and the
right side end of the rear part of the shutter 100, touches, not
compresses, the first and second seal beads 21, 22 and the third
and fourth seal beads 23, 24. The first and second seal beads 21,
22 are provided on the upper wall 12 of the protrusion 11 of the
bed liner seal member 10. The third and fourth seal beads 23, 24
are provided on the side wall 13 of the protrusion 11 of the bed
liner seal member 10. With this configuration, the upper parts of
the rear ends of the left and right side walls 2, 3 of the cargo
bed 1 are sufficiently sealed, and infiltration of water into the
cargo bed 1 from the exterior of the automobile is prevented.
[0086] Another possible embodiment is that the shutter seal member
120, provided on the rear end of the shutter 100, makes elastic
contact with the tailgate seal member 6 as illustrated in FIG. 8,
not the tailgate 5 directly. The tailgate seal member 6 is provided
on the upper part of the front surface of the tailgate 5. With this
configuration, paint on tailgate 5, which is a member of the
automobile body, is prevented from peeling off.
[0087] Specifically, a hollow part of the shutter seal member 120
illustrated in FIG. 13, which makes elastic contact with the upper
part of the front surface of the tailgate 5 directly, is
miniaturized. Next, the tailgate seal member 6 is provided on the
upper part of the front surface of the tailgate 5. With this
configuration, the shutter seal member 120 makes elastic contact
with the tailgate seal member 6 when the shutter 100 is fully
extended.
[0088] More specifically, a flange is formed close to the upper
part of the front surface of the tailgate 5. The flange has an
opening on an upper part. The tailgate seal member 6 includes the
installation base member 6a and the seal lip 6b. The installation
base member 6a has the U-shape with an opening on the lower end and
couples to the flange. The seal lip 6b extends diagonally rearward
relative to the automobile body from the upper wall of the
installation base member 6a and makes elastic contact with the
upper part of the tailgate 5. When the shutter 100 is fully
extended, the shutter seal member 120 makes elastic contact with
the seal lip 6b, which makes elastic contact with the upper part of
the tailgate 5. As a result, the shutter seal member 120 indirectly
seals a space between the rear part of the shutter 100 and the
upper part of the tailgate 5 with the tailgate seal member 6
sandwiched between the shutter seal member 120 and the tailgate
5.
[0089] In addition, as measures against abrasion, the touch member
110 of the shutter 100 touches, not compresses, the seal beads 21,
22, 23, 24, which are increased in thickness and high in rigidity
and does not make elastic contact with lips or hollow members which
are reduced in thickness and low in rigidity. With this
configuration, the beads 21, 22, 23, 24, subjected to repeated
elastic contact over a long period of time, are prevented from
tears or damages. Even in case the beads are worn down, foams in
the beads 21, 22, 23, 24, which are increased in thickness and high
in rigidity as compared with the lips and the hollow members, are
hard to appear on a surface and do not degrade appearance.
[0090] In addition, as illustrated in FIG. 4, the first gutter 25
is formed beneath the protrusion 11 of the bed liner seal member 10
and is closer to the front part of the automobile body than the
protrusion 11. The first gutter 25 extends in the right and left
direction of the automobile body. The second gutter 27 is formed
beneath the third and fourth seal beads 23, 24 on the side surface
and is closer to the interior of the automobile than the side wall
13 of the protrusion 11 of the bed liner seal member 10. The second
gutter 27 extends in the front and rear direction of the automobile
body and is continuous with the first gutter 25. With this
configuration, water around the bed liner seal member 10 is guided
into the first gutter 25 and the second gutter 27. In addition,
with the configuration that the first and second seal beads 21, 22
are continuous with the third and fourth seal beads 23, 24, the
channel between the two beads weakens force of water which passes
through the channel, and guides water into the first gutter 25. As
a result, water is prevented from splashing. In addition, the hole
29, closer to the rear part of the automobile body than the second
gutter 27, drains water guided into the first and second gutters
25, 27 toward the exterior of the automobile. With this
configuration, water does not collect on the first or second gutter
25, 27 or overflow.
[0091] In addition, when the shutter 100 is fully extended, the
lower surface of the upper wall 111 of the touch member 110
touches, not compresses, the first and second seal beads 21, 22 as
illustrated in FIG. 10, and the outer side surface of the side wall
112 of the touch member 110 touches, not compresses, the third and
fourth seal beads 23, 24 as illustrated in FIG. 11. With this
configuration, the upper parts of the rear ends of the cargo bed 1
are stably sealed. Also, the lower surface of the inner wall 113 of
the touch member 110 makes elastic contact with the first wall 26
and the lower surface of the side wall 112 of the touch member 110
makes elastic contact with the second wall 28. With this
configuration, infiltration of water into the cargo bed 1 from the
first gutter 25 or the second gutter 27 is prevented.
[0092] In the present embodiment, as illustrated in FIG. 12, which
is an enlarged cross-sectional view of the side end of the rear
part of the shutter 100 taken along line XII-XII of FIG. 5, a space
S remains between the connecting part of the seal beads and a
connecting part of the upper wall 111 with the side wall 112. This
is because an inner-cabin side surface of the connecting part
between the first seal bead 21 and the third seal bead 23 is
chamferred off and has the round surface in rear view for the bed
line seal member 10 is formed by die-molding. On the other hand, an
outer-cabin side surface of the connecting part of the upper wall
111 with the side wall 112 is formed into a pin corner in rear
view, not chamferred off or formed into the round surface.
[0093] In case high pressure water splashes the automobile while
washing the automobile and advances toward the space S, the inner
wall 113 of the touch member 110 dams up water. The inner wall 113
is closer to the front part of the automobile body than the space
S. Also, the inner wall 113 is connected with the upper wall 111
and the side wall 112, the lower end of the inner wall 113 makes
elastic contact with the first wall 26, and the lower end of the
side wall 112 makes elastic contact with the second wall 28. With
this configuration, water flows along the first and second gutters
25, 27 and is certainly drained toward the exterior of the
automobile from the hole 29.
[0094] While in the present embodiment, the touch member 110 of the
shutter 100 touches, not compresses, the first and second seal
beads 21, 22 and the third and fourth seal beads 23, 24, this
should not be construed in a limiting sense. Another possible
embodiment is that the touch member 110 touches, not compresses, a
singular seal bead on the upper surface and a singular seal bead on
the side surface, which are continuous with each other. Still
another possible embodiment is that the touch member 110 touches,
not compresses, the singular seal bead on the upper surface or two
seal beads on the upper surface (the seal bead on the side surface
not provided). With this configuration also, an excellent sealing
function is achieved.
[0095] Still another possible embodiment is that the first and
second gutters 25, 27 are not formed.
[0096] While in the present embodiment, a space remains between the
tail gate 5 in the closed position as illustrated in FIG. 3 and the
left or right track 201, 301, this should not be construed in a
limiting sense. Another possible embodiment is that a sealing
member is provided in the space.
